1 Answer

Answer:

2) The number is 4, 3) The number is 36, 4) The number is 16, 5) The number is 32, 6) The consecutive numbers are 14 and 15, 7) The solution of this system is:
x = 17 ,
y = 13 , 8) The solution of this system is:
x = 58 ,
y = 60 .

Explanation:

Now we proceed to solve arithmetically on each statement:

2) Statement is incorrect, correct form is: Find
if the product of
by 12 is 48.

Mathematically speaking, we have the following formula:

$12\cdot x = 48$

x = 4

The number is 4.

3) Mathematically speaking, we have the following formula:

$(3\cdot x)/(6) = 18$

(x)/(2) = 18

x = 36

The number is 36.

4) Mathematically speaking, we have the following formula:

$(5\cdot x)/(4) = 20$

x = 16

The number is 16.

5) Mathematically speaking, we have the following formula:

(x)/(2) = 16

x = 32

The number is 32.

6) Let be
and
n + 1 , whose sum equals 29. Mathematically speaking, we have the following formula:

n + (n +1) = 29

$2\cdot n + 1 = 29$

n = 14

The consecutive numbers are 14 and 15.

7) Let be
and
the quantities of pink and yellow roses. Mathematically speaking, we have the following system of linear equations:

x - y = 4 (1)

x + y = 30 (2)

The solution of this system is:
x = 17 ,
y = 13

8) Let be
and
the numbers of grade 6 and grade 3. Mathematically speaking, we have the following system of linear equations:

x-y = -2 (3)

y = 60 (4)

The solution of this system is:
x = 58 ,
y = 60
